EXTENSION FEEDER.

Application filed `.'I'anuary 14, 1922.

To alla@ hom t may concern Be itknown that I, JOHN C. ToLLnrsoN, a lcitizen of the United States, residing at Kansas City, in the county vof Wyandotte, State of Kansas, have invented certain new and useful Improvements in Extension Feeders; and I 'do hereby decla-re the following to bc a full, clear, and exact ydescription of the invention, such as will enable others skilled in the art to whichit appertains to make and `'use the same. This invention relates to new and useful improvements in feeders and particularly to feeders for separators.'` j The invention is an improvement over my pending application for an extension feeder, filed July 28, 1920, Ser. No. 399,592.

vOne object of the invention is to provide a feeder which can be easily and quickly '20 coupled to the feed end of a separator and .whichcan be readily folded and' unfolded. l Another object is to Aprovide `a feeder of this character whichcan be automatically folded and unfolded, bythe driving power from the separator. a

i kA. further objectisto. Vprovide a feeder of this character wherein is contained means for shifting the 'driving power from the feeding apron or belt `to the mechanism for folding and unfolding the frame of the feeder. y Y H ,y

`A still further obj ectis to provide a feeder of .this =character which hasl folding sidej boards, and wherein ftheside-boards are automatically folded and unfolded as the feeder frame is folded or'unfolded. Y

Other objectsand advantages will be apparent from the following description when l, taken in connection with the accompanying drawings.

Figure 7 is a vertical transverse sectional view through the outer end of the outer section of the feeder frame, with certain parts shown in elevation.

Referring particularlyto the accompanying drawings 10 represents the running gear of the feeder which has its outer end supported by the ground wheels 11, 'and has its other end to the axle 13 of the feed end of the separator 1.4. On the running gear are mounted the uprights 15 which support the longitudinal and downwardly and out-V wardly inclined frame 16, which has the side boards 17. Supported in 4the sides of the upper end of the frame '16 is the transverse shaft 18, on the opposite ends of which, and inwardly of the sides 17 are mounted the sprockets 19. Pivotally connected to the outer 'end ofthe frame 16 is the eXtension section 20, and inthe outer end of this section is mounted the transverseV shaft 21 having the sprockets v22, and engaged around the sprockets 19 and` 22 are the endless chains 23 which have the connecting slats 2li, and `the grain gripping means 25, de# scribed in the prior application, hereinbefore-mentioned, and 4forming the subjectmatter of a `separate application filed September 7 1921, Ser. No. 498,981, Y divided out of the said prior application. The pivot of the section 20 consists of the transverse shaft l26, and on each end of this shaft, outwardly ofthe side-boards, are the gears 27. Extending through 'the lower end Yof the frame 16, adjacent the shaft 2G, and parallel thereto, is a 'transverse shaft 28, which has on its ends the 'sprockets 29 'and the gears 30, the latter of which mesh with the gears 27. Extendingthrough the frame 16, above the inner upright 15, is a shaft 31 having on its ends the sprockets 32 and the gear 32. Engaged around the sprockets 29 and 32 are the chains "33, to which reference will be made later herein.

Mounted onlthe upper end of the frame 16 is a rack segment- ?A, and Ypivotalljv mounted on this segment is a 'lever 35. Above the pivot of the lever there is mounted an idler gear 36, and on the lower end of the lever, below `thepivot thereof, is a second idler gear 37. Extending transversely through the frame 16, adjacent the pivot of the lever 35, is a shaft 38, and on one end of this shaft there is mounted a combined which has on one end the bevel gear 40 which meshes with a similar gear V47 on the lower end of the shaft section/41, The bevel gear 40 has an' integralfspur gear 39 with which the gear 37 is arranged to mesh when the lever 35 is'rocked onI its pivot,A The lever has a spring pressed plunger pawl 49 which is arranged vfor interchangeable re ception in the notches 50 offthe rack Ysegment 34.` Slidable in brackets 51, on the side ofthe lower end ofthe frame 16, is a bar 52 theouter end of Vwhich is -forined with a toothed rack153which1mcshes with the gear 27.- Adjacent the -upper end vof the frame 16 is a', transverse shaft 54 which has the pulleys 55 on 'its ends, A and engaged around each of thesepulleys is a cable`56, one end of said cable being connected to the adjacent end of the bar 52, while the other end passes over the shafts 26 and 28 and aroundv a gTooved wheel 57, mounted on the side of thelow'er section of the feeder, and thence around two vertically alined pulleys 58, mounted on a bracket 59, where it is secured to the uppermostof the foldable sideboards 17'); Springs 60 are connected to the side walls of the said lower section of the feeder frame 16, and to the foldable boards 17,', so Ithatwhen released they will automaticallyfold themselves down onto the top of the apron of the conveyor of the chute.

`O nthe ends of the lower shaft 21 are gears 61 wliic'lrare disposed outwardly of the side-board of the section20. On the said side-boards, above and below the ends of theshaft and the said gears 61, are the longitudinal guides 62, and slidable in each pair of guides is a yokeI 63, the inner face of the lower leg of each of which is formed with rack teeth 64 which mesh with the lower side of the gear 61. At the inner ends of each pair of the guides 63, there is mounted a bracket 65, through which is slidably disposed the rod 66 carried by the inner end of the yoke 63, a coil spring 67encircling each of these rods and bearing against the yoke andthe bracket. On one end ofthe shaft 21 there is secured a worm gear l68 which is meshed by the worm 69 mounted in suitable brackets 70, above the upper guide. A hand-wheel 71 is mounted on one end of the worm for manual manipulation to turn the worm and cause, the yoke to slide in the guides, so" that the'shaft 21 may be moved bodily for regulating the tension of the conveyor apron. Y spring pressed supporting. leg72 is pivotally car'-v ried by each side of the lower end of the section 20, for engagement with the ground to support the said end of the section above the o-round.

Mtbunted on one side of the section, 17 lis a bracket 73, and'secured at oneend tothis bracket is a coil spring 74. Connected to the other end of the spring, and extended to and secured to the axis of the gear 27, is a cable 75. y 4 y `It will be noted that the rack segment 34 is inthe form of achannel, and that there isa curved member 76 disposed in this channel, said curved member having a pair of oppositely directed arrow portions 76',

which yare arrangedto lift the pawl 49, of

the lever 35, out of the notches, and permit the lever to swing on its pivot and` release the gears from their driven engagement with the thrasher. The otherfend vof this curved member 76 is connected with the adjacent end of thebar 52, by means ofthe rod 77. Thus, `when the `section 20 nears its completely folded position,the rod `52 will push the rod 77, and consequently the' curved member 76, so that the pawl of the lever 35 will be released from the notch of the segment, andthe power whichserves to fold the section 20, thrown out of gear. Y

As clearly'seen invFigure` 2, the shaft 28 is formed lto receive 4the crank handle .78, wherebythe sections may be folded by hand, when power is not available What is claimed is:l l l 1. An extension feeder comprising aportable support, a pair ofr foldable sections mounted on the support, an endless con: veyor onthe sections, means for operatively connecting thek conveyor with they driving mechanism ofv another machine, andmeans for automatically folding the Asections through the medium of the driving means of the other `machine 2. An extension feeder for, a thrashing machine comprising foldable conveyor carrying sections, one of the Asections having spring pressed foldable iside-boards,I said side-boards being self-foldingwhen the seclio tions fold, and means operable upon unfold;

nected respectively' with the rack bar and with the foldable side-boards, whereby when 15 the sections move toward folded position the 'boards will be permitted to fold, and when the sections move toward unfolded position the cable unfolds said boards.

In testimony whereof, I atlix my signa- 20 ture, in the presence of two witnesses.

JOHN C. TOLLEFSON.
